Upload File Using Net::HTTP to ROR App.

I can submit a zip file using a form to an ROR application. But I
need to be able to do this with a program so I am planning on using
Net::HTTP. I am debugging it on a PC using Webrick. I create a
multipart file (shown below). I use the following command to send the

response = Net::HTTP.start("localhost", 3000).post("/upload/upload",
query, "Content-type" => "multipart/form-data; boundary=" + boundary +
" " )

There is a controller called app/controllers/upload_controller.rb.
There is method in the controller called upload.

For some reason the server cannot find /upload/upload. Here is a
truncated error log. I have tried everything I know to try. Any
ideas on this.

#<TypeError: can't dup NilClass>

query is the info below. I tried various mime_types like application/
zip etc.

Content-Disposition: form-data;name="commit"
